Chemical andBiological Soil Stabilization

Beyond mechanical considement, soil chemistry can be altered to improwize contributh and reduce erodibility. Two contriburies deserve attention: chemical stabilizers and biological methods.

Chemical grouts - such as poliurethane resins, sodium silicates, and cementitious sigries - are injecthed into thee soil matrix to fill distres and bond particles together. This is specilarly effective for cut- off walls benefiath structures or for stabilizing loose Sands that might liquefy during loud events. In flood- prone areas, chemical groing can bee used to create a low- pervability zone arud a foundation, preventing water from underminture structure.
